Creating a function to plot multiple column of a variable in workspace

I have a array which is 729 by 9

.

.

.

.

Currently I am plotting the different columns in the same plot using the follow command:

.

plot(wavelengtha(:,1), Raman);

hold on;

plot(wavelengtha(:,2), Raman);

hold on;

plot(wavelengtha(:,3), Raman);

hold on;

plot(wavelengtha(:,4), Raman);

hold on;

.

.

.

.

plot(wavelengtha(:,9), Raman);

.

. This is still manageable as its only 9 columns. however in later stage, I will have arrays stretching up to 100+ columns. I was thinking of putting the above code in function. Where I will then key in the name of the variable to plot all the columns as y-axis.

. Can Someone help me with this?

Just use a for-loop for this purpose:

   for k = 1:n
     plot(wavelengtha(:,k), Raman);
     hold on
   end

What could be simpler?

But how do i write them in function. Because I got a list of wavelength.

wavelengthx_50

wavelengthx_49

.

.

.

wavelengthx_1

So i was thinking of writing a fucntion where i will input the eg. wavelengthx_48

and it will plot out the Figure(wavelengthx_48).
